What is ORA-06512? How can I rectify it?
The 06512 error is just informational and should accompany the "real" error message (usually just preceding the 6512 error line). This series of messages is often referred to as the "message stack." The Oracle Error Messages guide says the 6512 error is a: "Backtrace message as the stack is unwound by unhandled exceptions."
So, you don't rectify the 6512, you rectify whatever error precedes it in the stack.
